Answer:
So in exponential form
will be equivalent to 
Step-by-step explanation:
We have given the expression in radical form as 
We have to find its equivalent in exponential form
We know that if any fraction is in radical form then if we write this in exponential form then in exponential form the exponent come inverse of its number
So
can be written as 
So in exponential form
will be equivalent to 
For normal distribution 95% lie in the range mean-2*standard deviation for lower bound and mean+2*standard deviation for upper bound.
Upper bound is 78+2*6=78+12=90
Lower bound is 78-2*6=78-12=66
B. 66 and 90
Answer:
i can't explain how but the answer is:
3.98 * 10^8
Answer:
D) x^2+2
Step-by-step explanation:
(2x^2+2x+3)-(x^2+2x+1)
2x^2-x^2+2x-2x+3-1
x^2+3-1
x^2+2
